SAFETY IN HANDLING MAGNETS
MAGNET INFORMATION WARNING SHEET – M21.798
In some circumstances strong permanent magnets or magnetic assemblies can be dangerous or cause injury or
inconvenience to persons or property. This warning must be read prior to operating a permanent magnet or
magnetic assembly.
1. Accidental Injuries caused by handling Permanent Magnets.
Magnets can fly together or to steel objects causing severe pinching or lacerations to the skin.
Magnets can shatter on impact causing eye injury. Goggles must be used when handling.
Children must not be permitted to handle or play with Magnets.
Avoid flame or oven heating, grinding or cutting of Magnets. These procedures carry a risk of oxygen absorption
and possible shattering. Enclosed magnets if heated may explode.
2. Other Health Considerations.
Long term daily handling of Permanent Magnets may represent a health risk. These health risks are discussed in
British Pre-Standard No. 50166-1. We conclude from this Standard that there is usually no danger to operators
occasionally cleaning or handling magnets with static magnetic field levels up to 20,000 gauss or 2 Tesla. A more
recent paper INCIRP “Guidelines on limits of exposure to static magnetic fields” can also be referred to on this
subject.
HOWEVER AS A PRECAUTION WE RECOMMEND:
1. AVOID UNNECESSARY HANDLING, UNINFORMED HANDLING AND ASSEMBLY OF MAGNETS.
2. AVOID LONG TERM CLOSE BODILY CONTACT WITH STRONG MAGNETS.
3. KEEP STRONG MAGNETS AWAY FROM HEAD, EYES, HEART AND TRUNK.
4. CONTINUOUS DAILY EXPOSURE SHOULD NOT EXCEED 2,000 GAUSS OR 0.2 TESLA.
5. MAXIMUM ONE OFF EXPOSURE SHOULD NOT EXCEED 20,000 GAUSS OR 2 TESLA.
6. PERSONS WITH CARDIAC PACEMAKERS, OTHER SENSITIVE DEVICES IMPLANTED IN THE BODY
OR METALLIC PROSTHETIC IMPLANTS MUST NOT HANDLE OR COME INTO CLOSE PROXIMITY OF
MAGNETS. SPECIALIST MEDICAL OPINION MUST BE SOUGHT BEFORE SUCH PERSONS HANDLE
OR COME INTO CLOSE CONTACT WITH MAGNETS OR MAGNETIC FIELDS.
7. PERSONS WITH CARDIAC PACEMAKERS MUST NOT ALLOW MAGNET WITHIN CLOSE PROXIMITY
OF THEIR CHEST OR BE IN AN ENVIRONMENT ABOVE .5mT (5 gauss).

8. AS A GENERAL GUIDE, PERSONS WITH CARDIAC PACEMAKERS SHOULD AVOID COMING
CLOSER THAN 300MM FROM THE WORKING OR FIELD THROWING FACE OF MAGNETS SUCH AS
SMALL PLATE MAGNETS, GRATE MAGNETS, PROBE MAGNETS, MAGNET BARS, SPHERICAL
MAGNETS, ETC.
NOTE: THERE ARE OTHER MAGNETS SUCH AS SUSPENSION MAGNETS, MAGNETIC DRUMS AND
PULLEYS, OVERBAND AND CROSSBELT MAGNETS, ETC WHICH COULD REQUIRE THE MINIMUM
DISTANCE TO BE UP TO 2 METRES. WHERE IN DOUBT A GAUSS CHART SHOULD BE
UNDERTAKEN.
3. Damage to Electronic Equipment.
Permanent Magnets can cause damage to electronic equipment such as
a) Phone cards
b) Smart cards
c) Credit cards
d) Computer discs
e) Video, audio and computer tapes
f)
Computer equipment
Close contact can erase stored information. Keep Magnets away from electronic equipment. (N.B. We can advise
on insulation of vulnerable items.)
4. Transport of Magnets—”Dangerous Goods”
a) Strong Magnets may affect navigation instruments in aircraft.
b) If air-freighting Magnets advise freight agents and airline and consult your Dangerous Goods Management
Authority. Magnets should usually be road-freighted and freight company must be provided with a copy of
this “Safety and Handling Magnets” sheet.
c) We can advise on or provide special insulation packaging which satisfies transport regulations.
